BRAHMAN

That in whom reside all beings and who resides in all beings, who is the giver of grace to all, the Supreme Soul of the universe, the limitless being — I am that. Amritbindu Upanishad


 That which permeates all, which nothing transcends and which, like the universal space around us, fills everything completely from within and without, that Supreme non-dual Brahman — that thou art. Sankaracharya
